RAILWAY-TIE.

Specification of Letters Patent.

Patented Feb. 16, 1915.

Application filed August 24, 1914. Serial No. 858,218.

To all whom it may concern:

Be it known that I, THOMAS M. DANIELS, a citizen of the United States,and a resident of Chicago, in the county of Cook and v State ofIllinois, have invented certain new and useful Improvements inRailway-Ties, of which the following is a specification.

My invention relates to railways, and the object thereof is to provide atie for the tracks which not only positively maintains the tracks inrelationship with each other, but which also support the tracks in ayielding or resilient manner.

A further object is to adapt said ties for use in connection with woodbuffers, and also for use in connection with concrete, without alteringthe principles of the 1nvention; and further objects are to provide suchties which are positive in results, practically immune from raildisplacement, readily installed and removed, and comparativelyinexpensive.

My invention is fully described in the following specification, of whichthe accompanying drawings form a part, in whlch the separate parts aredesignated by the same reference characters in each of the views, and inwhich Figure 1 is a side elevation of one form of my tie, partly insection; Fig. 2 is a plan view thereof, with certain parts removed; Fig.3 is a view of one end of a modification, not all of the parts beingshown; Fig. 4 is aside View of the form shown in plan in Fig. 3; Fig. 5is a side elevation of the tie as employed with concrete; Fig. 6 is aplan view thereof, partly in section; Fig. 7

is a side view of the main or body portion of the tie shown in Fig. 5,detached; Fig. 8 is a bottom plan view thereof; and Fig. 9 is a planview of the skeleton employed in making the concrete foundation for thetie. In Figs. 1 and 2, I have illustrated one form of my invention,comprising a base 10 provided with four housing cups 11 for coil-springs12 arranged in pairs, one pair being beneath each rail, and said base isalso provided with a pocket 14, between the cups of each pair, and ineach of which is arranged a block 15, of wood or other suitablematerial, directly beneath each rail.

Above the base 10 is a stretcher 16, comprising a bar 17 in the axialplanes of corresponding cups of each pair of cups, and which stretchercarries an inverted cylindrical cup 18 telescoped over the correspondmgbase cup 11, and slidable vertically thereon, the corresponding spring12 supporting the several ends of the two stretchers of each tie, andrail clamps 19 are detachably held, by means of bolts 20, on the upperside of the stretcher 16, these being removed from Fig. 2, but one beingclearly shown in Fig. 1, and it will be seen that these clamps preventmovement of the rails toward each other. The stretcher 16 is alsoprovided with an upwardly and outwardly directed arm 21, at each endthereof, of such length as to bear against the fish-plate of the tracksin the positions of rail joints, and

I provide an extension 22 for use between fish-plates, so as to insure aside support for the rails, these extensions being readily removable andheld in position in any desired manner.

By reference to Fig. 1 it will be seen that the fit betweencorresponding cups 11 and 18 is a close one, being in fact air-tight,and I provide a check-valve 23 in the position of each of a plurality ofair-vents 24:, one for each set of said cups, and the effect of which isto prevent air from escaping from the said cups when depressed by theweight of a train to form an air-cushion within said cups, but air maypass into said cups freely in the upward movement of the cups 18, and Imay, if desired, employ small air-holes 25 to decrease the resistingeffect of the air-cushion, or any suitable equivalents for the holes 25.

Secured to the outer side of each of the cups 18 are two sets of twoinwardly turned projections 26 jointly forming sockets adapted toreceive short, oppositely directed, lugs 27 on corresponding rail clamps28 which are of such length as to bear against the outer fish-plates ofthe rails, and an extension 29 is provided for the rail clamps betweenthe fish-plates to insure an external support for the rails; the railclamps 28 are held in position by means of the lugs thereon, but I alsoprovide small plates 30 for this purpose, one on each side of each railclamp, and the two held together by means of a bolt 31 passed throughthe corresponding clamp, and I also provide a clamping plate 32 held inposition on each rail clamp by means of a bolt 33 for the outer sides ofthe rails, and it will thus be seen that the rails are immovably held onthe tie.

The tie is shown in Fig. 1 in depressed position by the weight of atrain passing thereover, and it will be seen that the coil-springs andthe aircushions in the four sets of cups take the weight resiliently,and the parts return to normal position as soon as the train has passed;in the event of any or all of the coil-springs breaking, the rails maysettle but only as far as the buffers 15 which then support the load, sothat no dangerous settling of the rails can occur.

In Figs. 8 and 4, I have shown a flat spring 34 which may be used inconjunction with the coil springs described, these flat springs beingarranged in the positions of the wood buffers referred to, andpreferably thereover, and they may be held in position by means of smallclamping plates, not shown, or in any other desired manner, the effectof which fiat springs is, obviously, to distribute the load over severalresilient supports for the rails.

The construction shown in Figs. 5 to 9, inclusive, is intended for useas a concrete tie, and comprises a base formed of a bar 85 having twomembers 36 riveted thereto at 37, Fig. 9, said members being channeledas shown at 38 and being provided, each, with two sets of oppositelyarranged, vertical, slots 39 adapted to receive the corresponding tongue40 of two sets thereof on each of two stretchers 41, whereby saidstretchers are capable of vertical movement at each end thereof, acoil-spring 42 being arranged beneath each end of each stretcher, withinthe corresponding channel 38, and held therein by means of lockingplates 43, Fig. 6; in this form the concrete is poured around the baseformed by the bar 35 and members 36, in a form indicated by dotted linesin Fig. 9, thus producing a reinforced concrete base for the operativeparts thereover. The outermost tongues 40 of the two stretchers 41 areeach provided with lugs 44, forming pockets similar to those formed bythe lugs 26, for engagement with the rail clamps 45 in all respectssimilar to the rail clamps 28 already described, plates 46 holding thesame in position, and clamps 47 and bolts 48 holding the rails inposition, in the manner already described, and I also provide woodbuffers 49 in this form to take the load of a. train in the event ofaccident to the coilsprings.

The forms are all similar in the main features of rail positioning andresilient supports therefor, one modification, Figs. 3 and 4, employinga supplemental fiat spring beneath each rail, and the othermodification, Figs. 5 to 9 inclusive, disclosing a re-inforced concretebase in place of the cast steel base shown in Figs. 1 to 4 inclusive.

While I have shown these three forms, it will be obvious that otherforms thereof may be suggested to meet varying conditions, and, with areservation to myself of all such changes in and modifications of theforms shown and described, as come within the scope of the followingclaims, what I claim as new, and desire to secure by Letters latent, is

1. The combination with two rails, of a stretcher for maintaining saidrails in position, and an air-cushioning chamber at each end thereof forsupporting the same resiliently.

2. The combination with two rails, of a stretcher for maintaining thesame in position, an air-cushioning chamber at each end of saidstretcher, and a check-valve in said chamber.

3; The combination with two rails, of a stretcher for maintaining thesame in position, a base therefor comprising a bar, members thereonarranged beneath each rail, a concrete envelop for said bar and members,resilient supporting means interposed between said base and stretcher,and lllilllS for detachably holding said rails to said stretcher.

4. The combination with two rails, of a base, two stretchers for saidrails thereon, resilient supporting means interposed between said baseand each end of each stretcher, and a buffer arranged on said base,beneath each rail, and between said stretchers.

5. The combination with two rails, of a base, a stretcher verticallyguided thereon, resilient supporting means for said stretcher, saidstretcher comprising a central member for spacing said rails, anddetachable end members for clamping said rails to said central member.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
